Hey Klever @Validators !

The wait is over, and the next monumental leap forward for our network has officially arrived. We are absolutely thrilled to announce the release of Klever Blockchain Mainnet v1.7.16! This isn’t just an update; it’s a massive step toward a faster, more secure, and unstoppable decentralized future. The momentum we are building together is incredible, and the best is yet to come!

The absolute crown jewel of this release is the implementation of Reward Distribution V2! We have completely revamped how rewards are distributed at the end of each epoch, making the entire process significantly more performant, robust, and resilient than ever before.

But the innovation doesn’t stop there! This version is packed with under-the-hood power, featuring essential core optimizations and enhanced KVM capabilities. On top of that, we’ve massively leveled up our network’s connectivity with major WebSocket improvements and the highly anticipated addition of event support on the WebSocket!

If you want to dive into the nitty-gritty of all the tech magic we’ve packed into this release, check out the full details here:
